This works very well and I have only been using my gfo from brs. Very straight forward I run mine in a canister along with brs carbon in another canister I simply fill, install open my ball valve and rinse with tank water until dust particles at minimal or just until water comes out clear so it helps with a 1-2 gallon water change in my total 90g reef. Also I only have to change it every month and a half to two months on my bio load very good. Thanks BRS!

Started using this GFO in a BRS single reactor mixed with Carbon after having a green dust algae bloom in a newly established reef. I noticed differences the next day. Removing the phosphates completely killed off the algae within a week. Thanks for the advice BRS, good media!!!

I have this in a phosban 150 reactor along with the BRS lignite carbon, I am about a week in and once I got the flow right through the reactor I can tell an immediate difference. I was using seachem sea gel and it worked ok, but this combination works SOOO much better. Nuisance algae has been all but stopped. I used to have to scrape the tank sides about once a week, once I got this stuff up and running I can tell the growth on the glass has slowed WAY down. Phosphates were always pretty low in my tank, but this stuff has it basically at 0, or just above. I have not been running it long enough to probably get it all the way down yet. I not looking back I am going to run this stuff from now on.

Good Product

a mustBy Christopheron 12/24/2014

This works wonders if you follow the instructions. I've been running it for close to a year now, and it is a staple for sure. You must use the correct amounts, and you must change it out. Don't expect results if you are to frugal with it.

Been using a cup of this in my reactor for about two weeks and i can already see a difference in my tank. Algae is almost gone. Phosphates are virtually at 0 now. I will continue using this product as long as I have an aquarium.

I've been using this in a filter sock in my hob filter. Although not the most efficient use of GFO it still does a great job of keeping my phosphates low. I only wish I had a larger setup so I could use a media reactor.

Good stuff, a bit dustyBy Ryanon 12/10/2014

Just make sure you rinse it well before placing it in the system obviously. It does contain a fair amount of dust, but does the job once installed. No complaints here, you get a lot for what you pay for.

for the priceBy justynon 12/4/2014

A great product for the price. I run gfo a long side my carbon and changing this product out gets expensive, once I found out about BRS I was hooked with them.
